If you're a smoker (and even if she also is one), remember to chew a gum or a lime for a perfect smooch (but that what would come later in a date, a peck in the cheek is all you're going to get when you arrive at your venue.
Filipinas also have a habit at looking at a guy's fingernails (although they do it discreetly) so better trim them before you go out of your place. The Philippines is a predominantly Catholic country (it's around nine of out ten says the government, so chances are, you would be dating a Filipina (Pinay) Catholic). But I guess, even if you're both sober and not drunk, both topics are a definite no-no unless, of course, you have taken your relationship to a higher level.
Lastly, these tips - though unsolicited - would help you in your date with a Pinay.
If you are about to date a Filipina or Pinay (that's a slang term to mean a girl coming from the Philippines or with Filipino ethnicity) or if you are just planning to go on one, consider this unsolicited advice. The greatest turn-offs (not only for Filipinas but also for women of all cultures) are bad breath, body odor, untidy and smelly clothes, dirty fingernails, etc.
Here I am a 26yr old foreigner semi-fluent in Bisaya, basic knowledge of Tagalog who is living in the Philippines. I have met some Filipinas that right away make me wish I had the privilege of saying… It helps me inspire some positive thinking in the minds of people I look up to… I have found over the course of my time in the Philippines I have pushed away any opportunity I may have had to date a Filipina and to get close to a Filipina. In fact just a few days ago a foreigner told me: “You must be a big hit with the ladies. Get a few beers in you and I bet all the stories will come out.” Stories of a 26yr old who even though maybe lonely in that aspect of his life, just doesn’t agree with people focusing on being with girls here as being the best part of the Philippines. I completely understand why foreigners talk about the girls here so much, because they are amazing, and yes chances are you will get a lot of attention from them if you are a nice guy. One day we were hanging out looking for ingredients to make some food.
